TimeSpan.LessThanOrEqual Operator

Indicates whether a specified TimeSpan is less than or equal to another specified TimeSpan.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public static bool operator <=(
	TimeSpan t1,
	TimeSpan t2
)

Parameters

t1
Type: System.TimeSpan
The first time interval to compare.
t2
Type: System.TimeSpan
The second time interval to compare.

Return Value

Type: System.Boolean
true if the value of t1 is less than or equal to the value of t2; otherwise, false.

The following code example compares several TimeSpan objects to a reference TimeSpan using the LessThanOrEqual operator.


// Example of the TimeSpan relational operators.
using System;

{
   const string dataFmt = "{0,34}    {1}";

   // Compare TimeSpan parameters, and display them with the results.
